The mean is all of them added together divided by the number, so multiple the mean by the number of sides, 3, and that's the perimeter. 18 x 3 = 54
First put the equation in y=mx+b form then plot the b and count off the slope.
Answer:
56 units²
Step-by-step explanation:
Each triangle has an area that is ...
... A = 1/2bh = 1/2·7·4
There are 4 such triangles, so the total area is ...
... 4A = 4(1/2)·7·4 = 2·7·4 = 56 . . . . units²
_____
An area formula customarily used when the diagonals are pependicular to each other is that the area is half the product of their lengths.
... A = (1/2)d1·d2 = (1/2)·14·8 = 56
Answer:
aⁿ=4(−1)ⁿ⁻¹/3ⁿ
Step-by-step explanation:
use the formula an=a1rⁿ⁻¹
aⁿ=4(−1)ⁿ⁻¹/3ⁿ
